“…When colliding two intense pump laser pulses orthogonally, with frequencies ω 1 = 2ω 2 , a probe of the overlap can experience frequency up/down shifts at resonant axion masses [1063]. The diphoton coupling is also predicted to lead to parametric instabilities in the propagation of an intense laser pulse [1064] and a flux of ALPs being generated by a laser-driven plasma wakefield propagating along a constant strong magnetic field [1065]. The change in an x-ray beam (produced by a free electron laser) as it probes the quasi-static fields in hollow plasma structures, formed by colliding an intense laser pulse with a low-density target, has also been suggested as a probe of ALPs [1066].…”

Upcoming and planned experiments combining increasingly intense lasers and energetic particle beams will access new regimes of nonlinear, relativistic, quantum effects. This improved experimental capability has driven substantial progress in QED in intense background fields. We review here the advances made during the last decade, with a focus on theory and phenomenology. As ever higher intensities are reached, it becomes necessary to consider processes at higher orders in both the number of scattered particles and the number of loops, and to account for non-perturbative physics (e.g. the Schwinger effect), with extreme intensities requiring resummation of the loop expansion. In addition to increased intensity, experiments will reach higher accuracy, and these improvements are being matched by developments in theory such as in approximation frameworks, the description of finite-size effects, and the range of physical phenomena analysed. Topics on which there has been substantial progress include: radiation reaction, spin and polarisation, nonlinear quantum vacuum effects and connections to other fields including physics beyond the Standard Model.
